安卓 Facebook 分享 : activity not found

Question

我在 Facebook 上发布数据的功能有问题:

    public void postData() {
    try {
        Intent i = new Intent(Intent.ACTION_SEND);
        i.setClassName("com.facebook.katana",
                "com.facebook.katana.ShareLinkActivity");
        i.setType("text/*");
        i.putExtra(android.content.Intent.EXTRA_TEXT, "http://sample_url.com");
        startActivity(i);
    } catch (Exception e) {
        Intent i= new Intent(Intent.ACTION_VIEW);
        i.setData(Uri.parse("http://sample_url.com));
        startActivity(i);
    }
}

每次我收到有关 Activity com.facebook.katana.ShareLinkActivity 无法运行的信息时，我应该将代码添加到 Android list 中。手机上安装了 Facebook 应用程序。

在 AndroidManifest.xml 中:

    <activity android:name="com.facebook.katana.ShareLinkActivity" >
    </activity>

LogCat 异常:

Answer 1

最后我得到了这段代码:

        Intent sharingIntent = new Intent(Intent.ACTION_SEND);
        sharingIntent.setType("text/plain");
        sharingIntent.putExtra(Intent.EXTRA_SUBJECT, "Subject");
        sharingIntent.putExtra(Intent.EXTRA_TEXT, "Text...");
        sharingIntent.setPackage("com.facebook.katana");
        startActivity(sharingIntent);

要点是 setPackage 和 setType - 现在 Android 从 Facebook 包中选择正确的 Activity 。
